On Monday night at the council committee meetings, councillors voted to only put two of the options out for public consultation.

Councillors Stephen Lawrence, Jane Diffey and David Grant pushed for four, but the motion for an amendment was defeated.

Mayor Ben Shields said the two options going on public display - Minore Road to Sandy Beach Road/Bligh Street or Minore Road to South Street/Bligh Street - were the best options.

"The other two options, blind Freddy can tell they're ridiculous and the residents and businesses that are affected would be outraged. In a lot of cases they're not practical," Cr Shields said.

He said one of options not going on exhibition would "pick a fight" with Taronga Western Plains Zoo, because council would have to seize some of their land, and it would go through Dubbo Golf Club.

Meanwhile, he ruled out the fourth option as "ridiculous" because it would add more traffic to Tamworth Street.

"People who have been in Dubbo for a while will remember the great fight of 2015 when it was proposed to put more cars and denser housing into south Dubbo. We've already been told it's a no go to put extra cars into the south Dubbo areas," Cr Shields said.

Mr Saunders said there had been a lot of a people calling into his office and enquiring about council only releasing two options.

"The public should probably ring council and let them know that they are concerned," he said.

"If you want to have an open and transparent process, everyone in the community has the right to feel like they've been heard and every option needs to be on the table."

He said he was unsure, especially after the hammering he had copped over the River Street Bridge consultation, why council would have a "veil of secrecy" about the routes.

But Cr Shields hit back at the MP, saying he was "disappointed" he was playing games.

The proposal for the South Dubbo bridge - which is expected to cost between $33.9 million and $35.7 million, depending on which option is chosen - will go on public exhibition soon.

Following the public's feedback, another report will be prepared for the councillors.

The mayor said he was happy with either of the Minore options as they would help ease the congestion in west Dubbo.

Construction for the proposed South Dubbo bridge is not expected to begin for four to five years.
